Idle States (C-states) are used to avoid wasting power when the processor is idle. C0 is the operational state, that means that the CPU is doing helpful work. C1 is the primary idle state, C2 the second one, and so forth, where more power saving actions are taken for numerically upper C-states.
Enhanced Intel SpeedStep® Technology
Enhanced Intel SpeedStep® Technology is a sophisticated manner of enabling top performance even as meeting the facility-conservation wishes of mobile systems. Typical Intel SpeedStep® Technology switches each voltage and frequency in tandem between low and high levels based on processor load. Enhanced Intel SpeedStep® Technology builds upon that architecture the usage of design methods such as Separation between Voltage and Frequency Adjustments, and Clock Partitioning and Recovery.
Thermal Monitoring Technologies
Thermal Monitoring Technologies give protection to the processor package and the system from thermal failure via a few thermal control options. An on-die Digital Thermal Sensor (DTS) detects the core’s temperature, and the thermal control options cut back package power consumption and thereby temperature when required so as to stay inside of standard operating limits.
